The Vietnamese threat actors behind the Ducktail stealer malware have been linked to a new campaign that ran between March and early October 2023, targeting marketing professionals in India with an aim to hijack Facebook business accounts. "An important feature that sets it apart is that, unlike previous campaigns, which relied on .NET applications, this one used Delphi as the programming language," Kaspersky  said  in a report published last week. Ducktail , alongside  Duckport  and  NodeStealer , is part of a  cybercrime ecosystem  operating out of Vietnam, with the attackers primarily using sponsored ads on Facebook to propagate malicious ads and deploy malware capable of plundering victims' login cookies and ultimately taking control of their accounts. Such attacks primarily single out users who may have access to a Facebook Business account. The fraudsters then use the unauthorized access to place advertisements for financial gain, perpetuatin...

Vietnamese public companies have been targeted as part of an ongoing campaign that deploys a novel backdoor called  SPECTRALVIPER . "SPECTRALVIPER is a heavily obfuscated, previously undisclosed, x64 backdoor that brings PE loading and injection, file upload and download, file and directory manipulation, and token impersonation capabilities," Elastic Security Labs  said  in a Friday report. The attacks have been attributed to an actor it tracks as REF2754, which overlaps with a Vietnamese threat group known as APT32, Canvas Cyclone (formerly Bismuth), Cobalt Kitty, and OceanLotus. Meta, in December 2020,  linked the activities  of the hacking crew to a cybersecurity company named CyberOne Group. In the latest infection flow unearthed by Elastic, the SysInternals  ProcDump  utility is leveraged to load an unsigned DLL file that contains DONUTLOADER, which, in turn, is configured to load SPECTRALVIPER and other malware such as P8LOADER or POWERSEAL...

Are you using the cloud or thinking about transitioning? Undoubtedly, multi-cloud and hybrid environments offer numerous benefits for organizations. However, the cloud's flexibility, scalability, and efficiency come with significant risk — an expanded attack surface. The decentralization that comes with utilizing multi-cloud environments can also lead to limited visibility into user activity and poor access management.  Privileged accounts with access to your critical systems and sensitive data are among the most vulnerable elements in cloud setups. When mismanaged, these accounts open the doors to unauthorized access, potential malicious activity, and data breaches. That's why strong privileged access management (PAM) is indispensable. PAM plays an essential role in addressing the security challenges of complex infrastructures by enforcing strict access controls and managing the life cycle of privileged accounts. By employing PAM in hybrid and cloud environments, you're not...

A Vietnamese threat actor has been attributed as behind a "malverposting" campaign on social media platforms to infect over 500,000 devices worldwide over the past three months to deliver variants of information stealers such as  S1deload Stealer  and  SYS01stealer . Malverposting refers to the use of promoted social media posts on services like Facebook and Twitter to mass propagate malicious software and other security threats. The idea is to reach a broader audience by paying for ads to "amplify" their posts. According to  Guardio Labs , such attacks commence with the adversary creating new business profiles and hijacking already popular accounts to serve ads that claim to offer free adult-rated photo album downloads. Within these ZIP archive files are purported images that are actually executable files, which, when clicked, activate the infection chain and ultimately deploy the stealer malware to siphon session cookies, account data, and other information. ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday  added  a critical flaw impacting Oracle Fusion Middleware to its Known Exploited Vulnerabilities ( KEV ) Catalog, citing evidence of active exploitation. The vulnerability, tracked as  CVE-2021-35587 , carries a CVSS score of 9.8 and impacts Oracle Access Manager (OAM) versions 11.1.2.3.0, 12.2.1.3.0, and 12.2.1.4.0. Successful exploitation of the remote command execution bug could enable an unauthenticated attacker with network access to completely compromise and take over Access Manager instances. "It may give the attacker access to OAM server, to create any user with any privileges, or just get code execution in the victim's server," Vietnamese security researcher Nguyen Jang ( Janggggg ), who reported the bug alongside  peterjson ,  noted  earlier this March. The issue was addressed by Oracle as part of its  Critical Patch Update  in January 2022. Additional d...

Facebook on Tuesday revealed it filed two separate legal actions against perpetrators who abused its ad platform to run deceptive advertisements in violation of the company's  Terms  and  Advertising Policies .  "In the first case, the defendants are a California marketing company and its agents responsible for a  bait-and-switch  advertising scheme on Facebook," the social media giant's Director of Platform Enforcement and Litigation, Jessica Romero,  said . "In the second case, the defendants are a group of individuals located in Vietnam who got users to self-compromise their Facebook accounts and ran millions of dollars of unauthorized ads." As part of the fraudulent activity, the marketing company, N&J USA Incorporated, promoted the sale of merchandise such as clothing, watches, and toys through misleading ads that, when clicked, redirected users to other e-commerce websites to complete the purchase, only to either receive nothing or get d...

Cybersecurity researchers from Facebook today formally linked the activities of a Vietnamese threat actor to an IT company in the country after the group was caught abusing its platform to hack into people's accounts and distribute malware. Tracked as  APT32  (or Bismuth, OceanLotus, and Cobalt Kitty), the state-aligned operatives affiliated with the Vietnam government have been known for orchestrating sophisticated  espionage campaigns  at least since 2012 with the goal of furthering the country's strategic interests. "Our investigation linked this activity to CyberOne Group, an IT company in Vietnam (also known as CyberOne Security, CyberOne Technologies, Hành Tinh Company Limited, Planet and Diacauso)," Facebook's Head of Security Policy, Nathaniel Gleicher, and Cyber Threat Intelligence Manager, Mike Dvilyanski,  said . Exact evidence trail leading Facebook to attribute the hacking activity to CyberOne Group was not disclosed, but according to a descrip...
